小学科学教学从实践情况上看,存在着规范化,学科性缺失等问题,它们的存在将对学生理解科学教学内容,对科学的认知形成一定的阻碍,因此,实行小学科学理解性教学至关重要。对小学科学理解性教学在实际教学中的应用进行研究,结合实际教学案例,开展课堂教学设计,从而发展学生的科学认知,转变科学概念,引发深层次的科学理解。 From the perspective of practice, primary science teaching has some problems, such as standardization and lack of discipline. Their existence will hinder students’ understanding of science teaching and hinder their cognition of science. Therefore, the implementation of primary science understanding teaching important. This paper studies the application of science comprehension teaching in primary school in practical teaching, and combines the actual teaching cases to carry out the classroom teaching design so as to develop students’ scientific cognition, change the concept of science and trigger deep scientific understanding.
